ROTARY PUMP.

Application filed September 15, 1922. Serial No. 588,369.

To all whom it may concern:

Be 1t known that we, FRANK A. GILLESPIE,

CHARLES MEYER, and HENRY B. MEADE, citizens of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Rotary Pumps, of which the following is a specification.

Our invention relates to rotary pumps and particularly, although not necessarily, to pumps for effecting the elevation of mercury and similar liquids.

It is a purpose of our invention toprovide a pump of the above described character of simple, inexpensive construction which op erates to effectively elevate a body of mercury so that it is capable of being conveyed to a remote point.

Although we have herein shown and described only one form of rotary pump en1 bodying our invention, it is to be understood that various changes and modifications may be made herein without departing from the spirit of the invention and the spirit and scope of the appended claims.

In the accompanying drawings,

Figure 1 is a view showing in front elevation and partly in section one form of pump embodying our invention.

Fig. 2 is a central vertical sectional view of the pump and adjacent parts shown in Fi 1.

Feferring specifically to the drawings in which similar reference characters refer to similar parts, our invention, in its present embodiment, comprises a stator designated generally at S which is shown as supported upon beams 15. The stator S, in the present instance, is made up of two sections arranged one upon the other, and each section is composed of spaced plates 16 preferably, although not necessarily, formed of wood and maintained in spaced relation to each other by means of an annulus 17 formed of The plates 16 of each section are grooved to accommodate the annulus 17, and the plates are securely held in gripping position with respect to the annulus by means of bolts 18. The plates of one section are removably secured to the plates of the other section by means of connecting plates 19, and packing strips 20 are interposed between the confronting faces of the plates 16 to prevent the leakage of liquid from the stator.

To facilitate the assembling or disassembling of the stator, the annulus 17 is also made up of two sections, and this annulus co-operates with the plates 16 to provide a rotary chamber designated at 21 in which a rotor designated generally at R is'adapted to rotate.

The plates 16 of the stator are recessed in their confronting edges and at corresponding points to receive a hub 22 which, as clearly shown in Fig. 2, constitutes a part of the rotor R, and through which a shaft 23 is extended. The hub 22 is arranged between a pair of bearings 24 bolted or otherwise secured to the beams 15 and through the bearings as well as the hub, the shaft 23 is extended and locked to the hub by means of set screws 25. The hub 22 constitutes a part of the rotor R, and as clearly shown in Fig. 2, the hub isprovided with annular flanges 26 secured to each other and to annular plates 27 by means of bolts 28. As clearly shown, the plates 27 are extended between theflanges 26 and into the hub 22 so as to provide a rigid connection between the hub and plates.

The outer ends of the plates nected by means of bolts 29, and arranged between the plates is a coil of pipe 30. As clearly shown in Fig. 1, the entrance end of the coil 30 is disposed at the periphery of the coil as indicated at 31, while the dis: charge end indicated at 32 is extended tan- 27 are congentially from the innermost convolution so as to have communication with the duct 33 of the shaft 28. This pipe-8O is preferably formed of copper and is. of uniform diameter throughout its length.

As clearly shown in Fig. 2, one end of v the shaft 23 is provided with a pulley 34-,

while its opposite end is adapted for vco-nsleeve 39 surrounds the shaft and is adjustable upon bolts 40 to compress the packing a within the casing. It is essential that the joint between the casing and shaft 33 be fluid tight to prevent the escape of li uid. and particularly mercury from the stui ng boX, and to this end the packing 38 is beveled at its side edges, as clearly shown in Fig. 2, so as to have contact with the bevel surfaces of the sleeve 39 and the inner end of the casing 37. When the sleeve has been properly adjusted, the packing serves to positively prevent the escape of fluid from the box.

In operation, the liquid to be elevated, such as mercury, is supplied to the rotor chamber 21 through a pipe 41 located at the bottom of the stator as shown in Fig. 2. The level of the mercury within the stator chamber is immaterial to the successful operation of the pump so that if necessary, the rotor chamber can be almost completely filled. 7 By applying power to the pulley 34L, rotation of the shaft 23 can be effected to impart a corresponding movement to the rotor R in a clockwise direction as when viewed in Fig. 1. Rotation of the rotor effects a forcing of the mercury into the entrance end 31 of the coil 30, and under the pressure set up by the rapid rotation of the rotor it will be clear that the mercury is forced to traverse the several convolutions of the pipe, and fall into the duct 33 of theishaft 24. From this duct, the mercury is forced to the discharge pipe 35 where it may be conveyed, to any suitable point,

What is claimed, is:

1. A rotary pump comprising a stator formed of sections arranged to provide a stator chamber, a rotor within the stator chamber and comprising a coil of pipe having its entrance end disposed at the periphery of the coil and its discharge end at the axis of the coil, plates embracing the pipe at the opposite sides thereof, a hub for sustaining the rotor, and flanges formed on the hub and connected to said plates.

2. A rotary pump comprising a stator in cluding separable sections each of the sections comprising spaced plates, a connecting member between the plates, and a rotor including a hub, flanges formed on the hub, plates secured to the flanges and a coil of pipe between the plates with an inlet end disposed at the periphery of the coil and a discharge end at the axis of the coil, and a shaft fixed to the hub and having a ductformed therein which is in communication with the discharge 'end of said pipe.

3. A rotary pump comprising a stator formed of sections arranged to provide a stator chamber, a rotor within the stator chamber and comprising a coil of pipe having its entrance end disposed at the periphery of the coil and its discharge end at the axis of the coil, and plates embracing the pipe at the opposite sides thereof.

In testimony whereof We have signed our names to this specification.
